NEW YORK, Oct. 13, 2026 /PRNewswire/ -- A missed primary endpoint in the pivotal Phase 3 FURVENT trial of firmonertinib sent ArriVent BioPharma (NASDAQ: AVBP) shares down between 50% and 63% today, October 6, 2026, to a 52-week low near $12.09.

FURVENT is a global Phase 3 study of firmonertinib in previously untreated patients with EGFR exon 20 insertion-mutated non-small-cell lung cancer. Its primary endpoint was progression-free survival assessed by blinded independent central review. According to the Company's program update, FURVENT did not meet that endpoint. ArriVent reported some secondary-endpoint benefits and no new safety signals.

Firmonertinib is ArriVent's lead pipeline candidate, and the Company's SEC filings described FURVENT as a pivotal trial with topline data expected in 2026. Shares were down roughly 56.7% before the opening bell, and one report placed the intraday low at $11.88. Levi & Korsinsky, LLP is investigating potential securities law violations on behalf of AVBP investors.
